Contactor Overload Relays — Buying Guide

AgaCanGroup lists contactor and overload relays from Siemens, Lovato, Schneider Electric, RS PRO and ABB — thermal overload relays that protect motors against sustained overcurrent, and auxiliary/control relays used for switching and signalling in the same control circuits. The specification that has to match exactly is FLC, Full Load Current: the relay's trip range must bracket the motor's actual full-load current, not just its horsepower rating.

What to check when specifying contactor overload relays

FLC motor rating vs contact current rating The FLC rating sets the current range the thermal overload trips within, and must be selected — or dialled in, on adjustable units — to match the protected motor's nameplate full-load current, not oversized "to be safe," which defeats the protection.

Pole configuration This catalogue lists both 3-pole and 4-pole units; pole count must match the motor's phase configuration and the contactor it pairs with.

Normal state configuration A relay's contact configuration (for example 1NC, 3NO) describes which contacts are open or closed when de-energised — check this against what your control circuit or PLC program expects for run and fault signalling.

Control voltage The relay coil's control voltage (this catalogue spans 24 V to 690 V) must match your control circuit voltage.

Frequently asked questions

How do I match an overload relay to a motor? Read the motor's full-load current (FLC) off its nameplate, then select — or, on adjustable units, dial in — a relay whose FLC trip range brackets that figure. An undersized range trips nuisance faults under normal starting current; an oversized range won't trip in time to protect the motor from sustained overload.

What does "1NC, 3NO" mean on a control relay? It describes the relay's contact configuration: how many contacts are normally-closed (NC) versus normally-open (NO) when the relay is de-energised. Your control circuit or PLC program dictates which configuration you need for run and fault signalling — check this against your existing wiring or ladder logic before ordering a replacement.

Can I use a 3-pole overload relay on a 4-pole contactor? No — pole configuration has to match between the contactor and the overload relay it's mounted or wired to, for both physical fit and correct phase monitoring. This catalogue lists both 3P and 4P relay ranges.
