H- and J-Frame Circuit Breakers
Earth Leakage Module (ELM) for PowerPact H- and J-Frame MCCBs
The Earth Leakage Module (ELM) is an add-on module which, when connected to a PowerPact H- or
J-frame MCCB, provides low-level ground-fault sensing and ground-fault relay functions.
Because these ELMs are highly sensitive (30 mA to 3 A), they provide much greater protection than
GFMs (20 Amps to 200 Amps sensitivity). The ELMs provide greater protection of control circuits and
other sensitive equipment. The associated circuit breaker must have a 48 Vdc shunt trip), which may
be field-installed (kit S29392) or factory-installed (suffix –SP) in the H- or J-Frame circuit breaker.

At 250 A, the ELM250JD can be used with 80% rated circuit breakers only.
Adjustable ground-fault pickup levels as low as 30 mA
Adjustable ground-fault time delays from instantaneous to 500 msec
(time delay can be applied to any setting)
Integral ground fault push-to-test feature
Ground-fault indicator; pop-up button for local status and contacts for remote indication (to be used
only with the tripping option)
All ELMs are supplied for I-Line
the I-Line mounting feet
Three poles; 240 to 600 Vac maximum: 3-phase, 3-wire (no neutral) and 1-phase, 2-wire
applications
Line-power obtained through internal bus to provide power for electronics, shunt trip, and integral
test feature.
A shunt trip is required in the circuit breaker; it may be field-installed or factory-installed in the
PowerPact H and J circuit breakers.
