Allen-Bradley 193-EC2PB AC Motor Overload Relay

Allen-Bradley 193-EC2PB is a 1-pole electronic overload relay that provides current-sensing protection for small AC motors when paired with a compatible contactor. It covers a 0.4 to 2.0 A motor current and trips on overcurrent within that range to prevent overheating and damage. The EC2 designation indicates electronic current sensing rather than a traditional bi-metal thermal element, offering precise, repeatable protection. This overload relay mounts with Allen-Bradley contactors to form a compact motor-protection assembly and is designed for single-phase operation in control circuits where space is limited and reliable, adjustable overcurrent protection is required.
