Terasaki TL-225B

Terasaki TL-225B is a heavy-duty moulded case circuit breaker from Terasaki TL series, widely used for marine low voltage power distribution systems. The moulded case circuit breaker is available in 3-pole configuration with frame rating 225A and optional thermal-magnetic trip units. This moulded case circuit breaker provides overload and instantaneous short-circuit protection for generator feeders, bus tie circuits and large motor loads. The moulded case circuit breaker adopts marine-grade mechanical construction, suitable for installation inside ship switchboards.

This breaker provides thermal magnetic overcurrent protection for LV power circuit safety isolation. The thermal magnetic overcurrent protection uses thermal trip to respond to long time overload conditions. The thermal magnetic overcurrent protection triggers instantaneous magnetic trip when short-circuit fault occurs. The thermal magnetic overcurrent protection protects cables, busbars and downstream electrical equipment from damage. The thermal magnetic overcurrent protection supports optional accessories including auxiliary contact, shunt trip and undervoltage release.

This Terasaki spare is an essential marine power distribution spare for vessel switchboard maintenance and retrofit. The marine power distribution spare can replace damaged TL-225B breakers directly. The marine power distribution spare meets IEC and marine classification society safety standards. The marine power distribution spare is widely fitted on cargo ships, tankers and offshore supply vessels.

Terasaki TL-225B MCCB is a classic marine low voltage feeder protection device. It integrates thermal-magnetic trip function, cuts off faulty circuit quickly during overload and short-circuit events, and operates reliably under high humidity, vibration and salt mist marine engine room environments.
