ETI product serie
- Spring-Charging Motor: Used to charge the stored-energy closing spring. Available in various AC/DC voltages, including 110 V, 220 V, 24 V, 48 V, and 125 V.
- Closing Release: Used for electrically closing the circuit breaker. Available for AC/DC 110 V, 220 V, and DC 24 V, 48 V, 125 V, as well as AC 380 V and 440 V.
- Shunt Trip Release (SHT): Used for electrically tripping the circuit breaker. Available for AC/DC 110 V, 220 V, and DC 24 V, 48 V, 125 V, as well as AC 380 V and 440 V.
- Secondary Shunt Trip Release: An additional shunt trip release providing a second electrical tripping circuit. Available in the same voltage ranges as the primary shunt trip release. Note that the Undervoltage Release and Secondary Shunt Trip Release cannot be installed simultaneously.
- Trip Circuit Supervision: Monitors the trip circuit.
- Undervoltage Release (UVT): Trips the circuit breaker when the control voltage falls below the specified release threshold. Available for AC/DC 110 V, 220 V, and DC 24 V, 48 V, 125 V, as well as AC 380 V and 440 V. It cannot be used simultaneously with the Secondary Trip (SI) application.
- Auxiliary Switch (Auxiliary Contacts): The standard version of the ACB includes 5 pairs of auxiliary contacts (5 NO and 5 NC).
- Lifting Lugs: For handling and installation.
- Mechanical Interlock: Prevents specified combinations of 2 or 3 circuit breakers from being closed simultaneously, according to the selected interlocking scheme. This requires an external mounting kit and pre-installed components within the main unit (specified with 'B0' in the order code). External mounting kits are available for 2-way and 3-way interlocks for various frames and pole configurations, for both draw-out and fixed types.
- Interphase Barrier: Provides insulation between phases.
- ON/OFF Pushbutton Locking Cover: Prevents inadvertent or unauthorized operation of the ON or OFF pushbutton and can be locked with up to three padlocks.
- OCR (Overcurrent Release): Equipped with enhanced power monitoring capabilities, including temperature monitoring, fault recording, and data storage. Various types (N, A, P, H) offer different protection functions and features. Depending on the OCR type, protection functions include long-time overcurrent, short-time overcurrent, instantaneous overcurrent, and ground-fault protection (L, S, I, G).
- Key Lock: Locks the circuit breaker in a specified operating position and prevents operation without the matching key. It is mounted on the main unit and ordered by adding "AB" to the order form. Two types are available: lock-in ON (locks the circuit breaker in the closed position) and lock-in OFF (locks the circuit breaker in the open position).
- Mis-insertion Prevention Device: Prevents incorrect insertion.
- Fixing Block
- ON-OFF Cycle Counter: A mechanical 5-digit counter showing the number of ON-OFF operating cycles performed by the ACB.
- OCR Alarm Switch Reset Button: Used to reset the overcurrent release alarm switch.
- Test Jumper: For testing purposes.
- Draw-Out Handle: Used to rack the draw-out circuit breaker between its operating positions.
- Undervoltage Release Time-Delay Controller: Used with the Undervoltage Release for time-delayed operation.
- Remote Closing Prevention Module
- Temperature Monitoring Module
- Short "b" Contact: Available only for automatic connection systems and attaches to terminals 51 and 52.
- Position Switch: Provides electrical indication of the circuit breaker's position in the cradle. It cannot be used in overlapping configurations and can only be installed on the right side of the cradle. Various types are available with different contact configurations for TEST, CONNECTED, ISOLATED, and INSERTED positions.
- Mechanical Interlock: Provides mechanical interlocking for up to 3 devices in both draw-out and fixed versions.
- Interphase Barrier
- Mechanism-Operated Cell Switch
- Mis-insertion Prevention Device
- Safety Shutter: Part of the standard specification.
- Arc Shield
- Control Terminal Cover: Available only for automatic connection systems.
- Switch-Disconnector Versions: Available for all current sizes.
- Customized Retrofit ACBs: Retrofit solutions can be developed to match the principal dimensions, pole configuration, primary connection arrangement, and other relevant interfaces of previously installed ACBs. This helps reduce the need for busbar and switchboard modifications and can minimize installation time and the duration of the required shutdown.
- Main Circuit Terminal Configurations: Horizontal and vertical terminal arrangements are available for EPL/EPH A-frame (630 A to 1600 A) and B-frame (2000 A to 3200 A) models. For currents above 4000 A, additional components are required. Front connections are also available for installations with restricted connection space.
- Door Flange: Provides IP20 degree of protection. For IP31 protection, a door flange with a gasket must be specified. An IP cover provides IP55 degree of protection.
- Dust Cover: IP52 rated.
- Voltage Module (EPLH-VM): Required when using high-end OCR types P and H.
- IR Temperature Sensor: Provides non-contact temperature measurement over a range of -5 °C to 250 °C. The recommended sensing distance is 50-80 mm. For accurate measurement, the target surface should be non-reflective; a matte black surface is recommended.
- Advanced Protection Functions: Depending on the OCR type, additional protection, monitoring, measurement, and diagnostic functions are available for demanding applications.
- 100% Neutral Current Rating: The neutral pole is designed to carry a continuous current equal to 100% of the rated phase current, supporting applications with load imbalance and single-phase loads.
