4-pole design TM LI trip unit Adjustable overload and short-circuit settings Standard breaking capacity (55kA) Unprotected neutral pole VL250N series

Product description

The Siemens 3VL3725-1EJ43-0AA0 is a VL250N series molded case circuit breaker with a 4-pole configuration and a rated current of 250A. It is equipped with a TM LI trip unit, offering adjustable overload (Ir) from 200A to 250A and short-circuit (Ii) from 1200A to 2500A. This breaker provides a standard breaking capacity (Icu) of 55kA at 415V AC and features an unprotected neutral pole.

This 4-pole breaker is suitable for applications requiring protection of all four conductors, including the neutral. It is commonly used in distribution systems where load balancing and protection are critical. The unprotected neutral pole is a key feature for specific system requirements.

Frequently asked questions

What is the function of the unprotected neutral pole on the Siemens 3VL3725-1EJ43-0AA0?

The Siemens 3VL3725-1EJ43-0AA0 features an unprotected neutral pole, meaning it does not have overcurrent protection itself. This design is typically used in 4-pole systems where the neutral conductor carries only the residual current or is not intended to carry significant fault current.
