ELRP48V-30 Type A Earth Leakage Relay

Type A – Earth Leakage Relay
Selectable Trip level (0.03 – 30A) and Time delay (0 – 10s)
Local (and optional remote) Test/Reset buttons
Isolated Auxiliary supply
1 x SPDT/1 x SPNO Relay outputs
48 x 48mm, Panel mount

This product is used in conjunction with an external Core Balance Current Transformer (CBCT) and will detect residual sinusoidal alternating and pulsating direct currents. An adjustable trip level and time delay allows the product to be set according to the type of installation to be protected. When the level of leakage current being monitored exceeds the set trip level, the unit will trip. Typically, the product is used in conjunction with an external switching device (i.e. contactor, shunt trip).

An auxiliary supply is required to power this product.

Key benefits:

Helps detect earth leakage — Type A residual-current monitoring can operate the relay output when leakage exceeds the 0.03 – 30A trip threshold.
Enables a control response — The relay output can be used with an appropriately specified contactor or shunt-trip device when a fault is detected.
Supports commissioning checks — Local and optional remote Test/Reset functions support commissioning and fault response.
Matches panel mounting — The 48 x 48mm format supports front-panel installation.
