Description

The Earth Leakage Module (ELM) is an add on module which provides low level ground fault sensing and relay functions. The add on ELM module features adjustable ground fault pickup levels as low as 30mA and adjustable ground fault delays from instantaneous to 500ms. It has an integral ground fault push-to-test feature. All ELMs are supplied for I-Line mounting and are convertible to unit mount by removing the I-Line mounting feet. A 48VDC shunt trip is required in the circuit breaker, either field or factory installed. This module has a rated operational voltage of 240 to 600VAC and current of 150 to 250A. The module complies with UL and CSA standards. The product comes as UL 1053 – Ground-fault Sensing and Relaying Equipment.

Features

The Earth leakage module is an add-on module for PowerPact J circuit breake, rated as 150 to 250A
ELMs are highly sensitive (30 mA to 3 A) and they provide much greater protection than GFMs (20 to 200 A sensitivity).
ELM fits in LA enclosure, I-line switch board and used with JD, JG, JJ, JL
At 250 A the ELM250JD can be used with 80% rated circuit breakers only
Dual interlock prevents cover from being opened (switch is ON)/prevents the switch from being turned ON (cover is open)
Horsepower rated for motor applications as 60 hp
Quick-make, quick-break operating mechanism.
Suitable for use as service entrance equipment
Red and black handle indicates the ON (red) or OFF (black) condition of the switch
UL listed, Seismically Qualified to the 2010 ASCE 7, 2012 IBC, 2013 CBC.
