Product details

Panel depth needs to accommodate the 130 mm depth behind the panel face.

Contact Ratings and Switching Capacity

Main contact ratings are given for several voltage levels: 6 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0 A at 690 V. The auxiliary contact block is attachable (1 unit). Maximum switching frequency depends on operating voltage: 100 operations per hour at 230/240/400 V, dropping to 30 per hour at 690 V. Operating time (AC and DC) is 30-55 ms; arcing time is 10-20 ms.

Conductor Connection

Solid conductors: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), 2x 4 mm². Stranded conductors: 2x (10-35 mm²) or 1x (10-50 mm²). At 40 °C, a single 35 mm² conductor is rated; at 60 °C, a single 50 mm² conductor is rated.

Frequently asked questions

What is 3RT2636-1NP35's depth for panel clearance?

The depth is 130 mm. This is the dimension behind the mounting surface and must be accommodated in the enclosure depth.

What conductor sizes does 3RT2636-1NP35 accept?

Solid conductors: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or 2x 4 mm². Stranded conductors: 2x (10-35 mm²) or 1x (10-50 mm²).

Where can I buy 3RT2636-1NP35 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote.
