Product details

It snaps onto a 35 mm DIN rail per DIN EN 60715 and can be screw-mounted as well, with a ±180° rotation on vertical surfaces and ±22.5° tilt forward/backward, so it adapts to tight enclosures without rework.

The DC switching curve drops to 2 A at 48 V and 60 V, and 0.9 A at 125 V — so if your line runs a higher DC bus, derate accordingly. On AC-3 duty (squirrel-cage motor switching) it manages up to 750 switching cycles per hour, which is typical for conveyor or pump cycling.

Width is 45 mm, depth 73 mm, height 58 mm — it occupies a single 45 mm DIN-rail slot. Wiring accepts solid or stranded conductors from 0.5 to 4 mm² (single wire) or two conductors per terminal (2x 0.5…1.5 mm², 2x 0.75…2.5 mm², or 2x 4 mm²). Screw-type terminals on the coil mean no special tooling for field termination.

Frequently asked questions

What is the closest functional alternative to 3RT2016-1BG42?

The 3RT2016-1BB41-ZW97 is a peer variant in the same S00 frame. The key difference is the coil voltage and terminal configuration — 3RT2016-1BG42 uses a 24 V DC coil with screw terminals; the -1BB41-ZW97 variant carries a different coil voltage and may include special markings. Both share the same Size S00 mechanical footprint and DIN-rail mounting, so a panel designed around one can accept the other with a wiring check on the coil circuit.

What is the depth of 3RT2016-1BG42?

Depth is 73 mm, width 45 mm, height 58 mm — fits a standard 45 mm DIN-rail slot.

What wire sizes does 3RT2016-1BG42 accept?

Solid or stranded conductors from 0.5 to 4 mm² single wire, or two conductors per terminal: 2x 0.5…1.5 mm², 2x 0.75…2.5 mm², or 2x 4 mm².
