Drawout circuit breaker 2000A 3P 85 kA OCR thermal-magnetic trip unit motor operator EPL-20 3H BD/M2C2S2/PR-LP 004695705

Professional Draw-out Circuit Breaker for Demanding Installations

The EPL-20 circuit breaker is an advanced protective device designed for the protection of transformers, generators, and extensive electrical installations in industrial applications. Thanks to its draw-out design, it enables easy servicing and replacement without the need to dismantle the entire installation - a key advantage in production environments where downtime is costly.

Technical Parameters and Construction

The device operates at a rated current of 2000A in a three-pole configuration, ensuring simultaneously very high short-circuit breaking capacity Icu = 85 kA at 400V. The rated operating voltage is 690V AC, and the rated impulse withstand voltage reaches 8kV, guaranteeing safe operation even under surge conditions.

The construction is based on the OCR (Over Current Relay) system with a rising current trip unit, enabling precise adjustment of protective parameters - thermal setting adjustable in the range of 0.4-1 xIn, and magnetic setting 1-15 xIn. The device features 5 changeover auxiliary contacts, as well as an integrated and optional motor drive for automatic control.

The draw-out design with main connections on the rear side simplifies installation in switchboard cabinets. The IP20 degree of protection ensures safe operation inside enclosures.

Normative Compliance and Operating Conditions

The circuit breaker meets the requirements of standard IEC 60947-2, confirming its compliance with European safety standards for electrical equipment. The integrated earth fault protection further enhances the level of installation protection.

The device weighs 88.93 kg with dimensions of 460 × 400 × 370 mm, reflecting its robust construction adapted for continuous operation in industrial applications. The manufacturer - ETI Polam Sp. z o.o. - provides full technical support and availability of spare parts over many years of operation.

The system is supplied complete with all protection elements and the optional motor drive, eliminating the need for additional purchases during standard installation.
