Tronic Thermal Overload Relay 30-40A
TSh 55,500
Our review
This Tronic thermal overload relay is a motor protection device that trips when current climbs beyond a set level, guarding windings and connected equipment against overheating and the damage that follows. Its 30 to 40 ampere range suits small to medium motors and machinery drawing current in that band, making it a sensible pick for workshops, pumps, compressors and similar driven loads. Before buying, confirm your motor's full-load current sits comfortably inside that range, since a relay sized too close to normal running current may nuisance-trip, and check the trip class and reset type your setup needs. Compare against overload relays with wider or adjustable ranges, and against electronic protection if you need finer tuning. Installation should follow the motor starter's wiring arrangement, so factor in how it mounts alongside your contactor. Available on Sokonia.
