Contactor VS Circuit Breaker: What’s The Difference - ALION

WebMay 26, 2024 · 1. Load Capacity The first difference among a relay and contactor is that both have different load capacities. Relays are used with electrical loads at a range of about 10 amperes or less, while a contactor load capacity is greater than 10 ampere. 2.Open/Closed Contact Standards WebOverload relay is required. An MPCB can protect a motor against overload and short circuit. MCCBs, when used in motor protection circuits can protect against short circuits only. Hence additional overload relay and contactor is required. A Motor can be directly turned ON and OFF manually using an MPCB, a contactor is optional. normal cholesterol levels cdc https://paintthisart.com
