T55-4-20.0A-01-11L Description

Short technical summary and product information.

The Sensata T55-4-20.0A-01-11L is a two-pole magnetic-hydraulic delay circuit breaker rated for 15A continuous current at 250V. It features a toggle actuator for manual on/off control and is designed for panel mounting. The hydraulic-magnetic trip mechanism provides time-delayed overcurrent protection, making it suitable for applications where momentary inrush currents must be tolerated without nuisance tripping.

 

This circuit breaker has no illumination and is supplied in a compact panel-mount package. The 2-pole configuration allows simultaneous switching of two conductors, commonly used in single-phase or dual-line applications.

 

Typical use includes overcurrent protection in power distribution panels, industrial control equipment, and commercial electrical systems. The hydraulic-magnetic technology offers stable performance across a wide temperature range without the need for thermal compensation.
