Product ID: WL series

Compact Elrs

The WL series Earth leakage relays(ELRs) are modular in design with snap on fixation on DIN rail. Complete with built-in differential core transformers. Available in adjustable current sensitivity and time delay settings.

• Rated voltage 180....250V
• Rated frequency 50/60hz
• Operating contact of the relay
• Change-over contact 3 Amp./250V
• Contact life duration: mechanical 20millions, electrical 100.000 minimum.
• Power(20celsius): rated 0.45W, maximum: 1,4 W-Dielectric resistance 750V. a.c. (50-60Hz) between open contacts. Trip out by under voltage coils and shunt trip coils.
• Weight: 175gr.
• Working temperature range -10celsius to +50celsius
• Supply voltage of test circuit: 220/240V
• Test: built-in test button. Also possible by external push-button

Features:

• Compact unit of relay and differential core transformer in insulated box
• Quick fixation on rail DIN 46277 or by screws
• Tripping time of relays adjustable between 0.02 and 1 sec.
• Remote control possible)disconnection and reset)
• Wide range of response values for all types, especially 0.005 Amp(high sensitivity). Response values fixed or adjustable on a wide range
• Internal diametre for 3 phases and neutral: Dia.25mm
• Maximum admissible section: 4 cables 25mm each
• Incorporated reading outlet: 1 mV(1m A leakage current equals 1 mV of outlet). Thus the leakage currents circulating through the differential transformer can be measured with any usual digital or analogue voltmeter with an input impedance higher than 10 k ohm/V
• For this reading it is necessary to use a plug type stereo jack

• Minimum Order: Negotiable
