ABB 1SDA059551R1 is a Moulded Case Circuit Breaker (MCCB) designed for advanced protection and monitoring of electrical circuits. It features pre-alarm and alarm LEDs, an alarm output contact, and provides detailed circuit-breaker status including open/closed positions through Modbus communication. The device allows for local or remote mode operation and enables setting of protection parameters, including overload (L), short-circuit with time delay (S), instantaneous short-circuit (I), and earth fault (G) protections, all configurable via Modbus. It records the last trip data and supports alarm and circuit-breaker reset through Modbus. The MCCB offers ring-lug or bar connections, with a rated current of 630A and a rated voltage of 750Vdc. Its control voltage stands at 690Vac, and it is designed for a 3-pole configuration. The device includes EFDP zone selectivity for enhanced protection and supports setting curves and protection thresholds through Modbus. It measures 205mm in height, 140mm in width, and 103.5mm in depth. The MCCB is capable of 5000 operations under load and has an electrical durability of 20000 operations for its analog outputs. It uses electronic technology with a PR223DS series and LSIG protection, without a display. The short circuit current breaking capacity is adjustable for overload, short-circuit with time delay, instantaneous short-circuit, and earth fault protections. It also features comprehensive measurement functions for monitoring electrical parameters and the system's operational status.
