Circuit breaker 1250A 3P 65 kA stationary OCR overcurrent release motor drive EPL-12 3H AF/M2C2S2/PR-LP 004695719

Professional solution for main switchboards

The EPL‑12 circuit breaker is an advanced protective device designed to protect electrical installations in main switchboards, at transformers, and generators. With a rated current of 1250A and a high breaking capacity of 65 kA at 690V AC, it ensures effective protection even in the most demanding industrial applications.

Advanced protections and adjustments

The device is equipped with OCR overcurrent protection and an instantaneous trip that reacts to rapid current increases during short circuits. The thermal setting in the range of 0,4‑1 xIn and the magnetic setting of 1‑15 xIn allow for precise adjustment of protection parameters to the characteristics of the protected installation. Integrated earth fault protection further increases the safety level of the entire system.

Construction and mounting capabilities

The circuit breaker is designed as a fixed-mounted device with rear connections, which facilitates cabling and ensures aesthetic mounting in switchboards. The pin connection guarantees reliable current conduction under high loads. The built-in motor operator enables automatic switching control and integration with building automation systems.

Operating parameters and standards

The device operates at a rated voltage of 690V AC and is characterized by high surge resistance - the impulse withstand voltage is 8kV. The IP20 protection rating ensures safe operation in switchboard conditions. The circuit breaker complies with the IEC 60947‑2 standard, confirming its high quality and reliable performance in difficult operating conditions.
