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.
Specifications:
- 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
Ordering information:
- Minimum Order: Negotiable set
