£4,236.26
The ABB 1SDA060251R1 is a high-performance SACE Tmax T6H moulded case circuit breaker (MCCB) designed to provide dependable protection for industrial and commercial low-voltage power distribution systems. Featuring a fixed four-pole construction, front terminal connections and a PR221DS-LS/I solid-state electronic release, it delivers accurate overload and short-circuit protection for demanding electrical installations.
As part of the proven ABB SACE Tmax T series, the T6H combines high interrupting performance with intelligent electronic protection. The PR221DS-LS/I release provides adjustable long-time, short-time and instantaneous protection functions, allowing engineers to improve selectivity, maintain system coordination and reduce unnecessary downtime across critical power distribution networks.
With a 630 A rated current, 690 V AC rated operational voltage and a high (H) breaking capacity, the ABB T6H is ideally suited to industrial switchboards, commercial buildings, manufacturing facilities, infrastructure projects and OEM electrical equipment requiring dependable circuit protection.
The ABB Tmax T6H automatically disconnects electrical circuits during overload and fault conditions, helping protect switchgear, transformers, cables and downstream electrical equipment. The PR221DS-LS/I electronic trip unit provides precise protection settings that improve discrimination and coordination throughout low-voltage electrical systems.
Designed for demanding industrial environments, the ABB 1SDA060251R1 delivers the interrupting performance, operational durability and protection reliability expected from ABB's internationally recognised SACE circuit breaker range.
