Protect critical three-phase circuits with precision using the Square D KAL361501027 150A 3-Pole 600V Circuit Breaker. Built by Square D, this robust 3-pole device is designed to safeguard electrical distribution systems against overloads and faults in demanding industrial and commercial environments. The part number KAL361501027 identifies the exact model, ensuring you get the right fit for compatible Square D panels and enclosures.

Key specifications at a glance:

• Current rating: 150 A
• Poles: 3
• Voltage rating: 600 V
• Part number: KAL361501027

Why this matters

This 3-pole configuration is ideal for protecting three-phase circuits, which are common in motors, conveyors, HVAC systems, and other heavy loads. A 150 A rating makes it suitable for main feeds or feeder protection within service panels that rely on reliable, predictable trip performance when electrical faults occur. With a 600 V rating, it can safely interrupt higher voltage networks typical in commercial and light industrial settings.

What sets it apart

• Brand reliability: Square D is known for engineering precision and consistent trip characteristics that electricians trust across installations.
• Exact fit: Part-specific design reduces guesswork during replacement, helping you maintain panel compatibility and electrical integrity.
• Durable construction: Built to withstand industrial environments where reliability matters most.

Ideal use cases

• Replacing a failing 150A, 3-pole, 600V circuit breaker in a three-phase panel.
• Feeder protection for three-phase equipment up to 600 V in commercial or light-industrial installations.
• Upgrading or stocking spare breakers for maintenance-ready electrical rooms and service panels.

Practical tips

• Verify that the panel is compatible with Square D KAL-series breakers and supports a 3-pole, 150 A, 600 V configuration.
• When replacing, follow manufacturer torque specifications and ensure secure, clean terminations to prevent loose connections.
• Keep the part number accessible in your inventory to simplify future maintenance and replacements.
