Protect your equipment from damage with this MCB from Rockwell Automation. It shuts down the power to attached machinery in the event of an overload or short circuit, preventing potential damage. A 3-pole configuration indicates this device can control 3 circuits simultaneously, so it's a good choice for busy setups with space limitations. The breaker exhibits type B characteristics, which means it's a fast-acting option that trips when the supply current is 3 to 5 times the full load current of the circuit. This component has a wide operating temperature range between -25ºC and +55ºC, so you can use it safely in harsh environments.

• DIN rail mounting with a fast clip for easy and secure attachment
• Current rating of 50A for use in high-powered applications

• UL
• CSA
• IEC/EN 60068-2-6

The Rockwell Automation Automation 1492-SPM supplementary protector is a 3 pole thermal magnetic circuit breaker which provides an overcurrent protection for equipment where branch circuit protection is already provided, or is not required. It has 50 amperes continuous current rating and trip curve B.

Current limiting
Fast breaking time
Superior shock and vibration resistance to prevent nuisance tripping
RoHS compliant and fully-recyclable device
Suitable for extreme ambient conditions

An MCB protects your equipment from damage due to current overload by tripping and interrupting the circuit. A fuse protects your machinery from overload by melting and breaking the circuit. You can reset and reuse an MCB, whereas a fuse needs replacing.
