Ground fault sensing and relaying equipment UL 1053
and CSA 22.2 No. 144 for North American and North American
influenced markets
The basic standard used to investigate products in this category is UL1053 "GroundFault Sensing and Relaying Equipment".
The Listing Mark of Underwriters Laboratories Inc. on the products is the only method
provided by UL to identify products manufactured under its Listing and Follow Up
The Listing Mark for these products includes the name and/or symbol of Underwriters
Laboratories Inc. (as illustrated on the label) together with the word "LISTED", a
control number and the following product name "Ground Fault Sensing and Relaying
This category covers ground fault current sensing devices, relaying equipment, or
combinations of ground fault current sensing devices and relaying equipment which
will operate to cause a disconnecting means to function at predetermined values of
ground fault current in accordance with the National Electrical Code, ANSI/NFPA70.
The RH99, RH21 and RH10 (M and P) ground fault relays are control powered
ground-fault protection devices used to protect an electrical distribution system from
ground faults. The relay receives input from sensors, processes the information and
if necessary closes output contacts which will cause the associated protection device
to trip.
The product is a class 1 combination ground fault current sensor and relay. This
equipment is intended to operate devices with shunt trip coils such as moulded case
circuit breakers, moulded case switches and the like, which constitute the
disconnecting means, by opening all ungrounded conductors at predetermined
values of ground fault current.
This product is designed to protect circuits of not more than 600 V AC, 50/60 Hz only.
The relay should be marked with the following electrical ratings, for the two types M
and P:
b type M: DIN format (Multi 9 type fast mounting or screw mounting)
b type P: front-panel mount (on panel, door, etc.)
b ratings:
v fixed I∆n threshold (a number of choices) and no time delay (instantaneous) or
v selectable I∆n threshold from 0.03 to 30 A and user-selectable time delay
from 0 to 4.5 s (see settings on pages 36 to 41)
b input voltages:
v AC: 20 to 24 V AC, 48 V AC, 110 to 130V AC or 220 to 240 V AC, 50/60 Hz, or
v DC: 12 to 48 V DC
b maximum consumption: 4 W.
