Product details

It carries 4 normally-open instantaneous contacts, rated 10 A in AC-12 duty (resistive/control loads). The 24 VDC coil draws a constant 3.2 W for both pick-up and hold, so there is no inrush spike to size your DC supply around.

Contact ratings — what the numbers mean

For inductive DC switching the numbers drop fast: 1 A at 110 V, 0.27 A at 220 V.

Screw and snap-on mounting onto DIN rail — the same 45 mm width as a S00 contactor, so it lines up mechanically. That matters when you are squeezing it into a crowded panel and the rail is not perfectly horizontal. The screw terminals accept 2x 4 mm² solid or 2x 2.5 mm² stranded — sized for control-circuit wiring, not power feed.

Pollution degree 3 (conductive pollution, typical for industrial control panels). Shock rated at 10g / 5 ms and 5g / 10 ms. RoHS compliance date is July 1, 2006 — the part meets the original RoHS directive.

Frequently asked questions

What is the closest functional alternative — 3RT1015-1BB42?

The 3RT1015-1BB42 is a power contactor, not an auxiliary contactor. It has a different coil voltage and contact configuration. The 3RH1131-1BB40-ZW97 is the dedicated auxiliary block for S00 contactors; a 3RT power contactor does not drop in without rewiring the control circuit.

What is the depth of this component?

The depth is 72 mm.

What wire sizes does the terminal accept?

Solid wire: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), 2x 4 mm².

What compliance documentation is available?

RoHS compliance is confirmed with a substance prohibitance date of July 1, 2006. The part carries IP20 front protection and surge voltage resistance of 6 kV.
