Industrial NB31200WK-S24-2A-2B 2A 3-Pole 240 V Circuit Breaker

Engineered for rugged industrial environments, the NB31200WK-S24-2A-2B is a 3-pole, 240 V circuit breaker that delivers precise overcurrent protection for three-phase power distribution. With a 2 A rating, it’s designed to safeguard low-current control circuits, automation panels, and small motors within industrial equipment, helping prevent downtime and equipment damage while keeping systems running smoothly.

• Current rating: 2 A
• Poles: 3
• Voltage rating: 240 V
• Part number: NB31200WK-S24-2A-2B
• Configuration: Three-phase protection suitable for 240 V industrial power distribution

Where it fits in your system

Ideal for industrial control panels, machinery enclosures, and electrical distribution setups that run on three-phase 240 V power. The three-pole design ensures all phases are simultaneously safeguarded, which is essential for protecting balanced three-phase loads and reducing the risk of partial fault conditions that can lead to equipment damage.

Why this specific unit stands out

Unlike general-purpose breakers, this NB31200WK-S24-2A-2B variant is tailored for industrial environments where reliability and traceability matter. Its distinct 3-pole, 2 A configuration provides targeted protection for small but critical circuits within automation and manufacturing settings, while its clear part number supports precise ordering, stocking, and replacement in busy maintenance workflows.

Practical use cases and scenarios

• Protecting a 3-phase control circuit powering a small motor or actuator in an automated assembly line
• Distributing and safeguarding 240 V loads in a compact industrial control panel
• Providing a reliable disconnect for three-phase auxiliary equipment in machine cabinets

Tips for optimal installation and operation

• Ensure the breaker is wired to protect all three live conductors in your 240 V three-phase circuit for complete protection
• Follow standard enclosure and terminal torque guidelines to maintain secure connections and reliable performance
• Keep a properly rated spare of the NB31200WK-S24-2A-2B on hand for quick replacement in critical systems
