ABB T5S630 SACE Tmax T5 series plastic-case circuit breaker

Product Description

T5S630 is a moulded case circuit breaker (MCCB) of ABB SACE Tmax T5 series, frame rating 630A. “S” stands for standard short-circuit breaking capacity. This circuit breaker can be equipped with TMA thermal-magnetic trip unit or PR221DS electronic trip unit, providing long time delay overload protection, short time delay short-circuit protection and instantaneous short-circuit protection. 3-pole or 4-pole versions are available, supporting fixed and plug-in mounting. It is used in low voltage power distribution systems for protection and isolation of cables, transformers and motor loads. Accessories such as auxiliary contacts, shunt trip and undervoltage release can be fitted. It is a widely used protective component and spare part for industrial switchgear and power distribution projects.
