Product details

Solid-state overload relay for contactor-mount integration

Its 3-pole configuration and screw-type main terminals with spring-loaded auxiliary terminals make it a direct fit for panel layouts where a contactor and overload relay share a common rail — no separate base or DIN-rail adapter needed. The ATEX Ex II (2) GD certification qualifies it for explosive-gas and dust atmospheres where a thermal bimetal relay might not be permitted.

Trip class and protection envelope

The 8 kV surge voltage resistance and EMC burst immunity of 2 kV on power ports and 1 kV on signal ports, severity degree 3, cover the relay against switching transients in industrial control panels.

Mounting position is any, but the fastening method is contactor mounting — it clips directly onto the contactor's front face, not onto a DIN rail. Main circuit accepts stranded conductors 2x (10 … 50 mm²) or single 10 … 70 mm², with AWG equivalents 2x (10 … 1/0) or 1x (10 … 2/0). Auxiliary and control circuit uses spring-loaded terminals accepting 2x (0.25 … 1.5 mm²) solid or finely stranded with ferrule, AWG 2x (24 … 16).

Frequently asked questions

What compliance documentation does the 3RB2046-1ED0 carry?

The relay carries ATEX certification PTB 06 ATEX 3001 Ex II (2) GD for explosive gas and dust atmospheres. It also has a substance prohibitance date of 07/01/2006, indicating RoHS compliance for that cutoff. EMC immunity is documented per IEC 61000-4-4 burst at severity degree 3.

Where can I buy the 3RB2046-1ED0 and how is it quoted?

The 3RB2046-1ED0 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are published here.

What is the 3RB2046-1ED0's depth dimension?

The listed depth is 124 mm. Width is 70 mm and height is 106 mm.
