FAQ
Q1: Is this just a separate ground fault module or a complete circuit breaker?
A1: It is an all-in-one complete circuit breaker with built-in overload, short-circuit and ground fault protection functions. It is not an add-on accessory and can be wired into the circuit directly out of the box.
Q2: Can it be used on 220V/380V circuits?
A2: Its rated voltage is 480V AC, and it is backward compatible with AC circuits of lower voltage levels such as 380V. All ground fault and protection functions work normally.
Q3: Is ELJBN3150W complicated to install?
A3: Not at all. This model features a modular design for the Series G / JG Frame system. It can be installed following standard circuit breaker procedures and fits standard industrial electrical cabinet structures.
Q4: How can I place an order or apply for bulk purchase discounts?
A4: Send your required order quantity via email to Irene8866@163.com, or leave us a message on WhatsApp (+86 18950163907). We will reply within 24 hours with formal quotation and stock confirmation.
