The Schneider Electric 18637 is a miniature circuit breaker (MCB) designed for robust electrical protection in demanding industrial environments. As a 3-pole (3P) device from Schneider Electric's established line of protective devices, this MCB is rated for 40A and features a C tripping curve, making it suitable for circuits where controlled surge tolerance is required before a fault trip occurs.

Technical Details

• Poles: 3-Pole (3P)
• Current Rating: 40A
• Tripping Curve: C Curve
• Voltage Rating: Verify with manufacturer datasheet; typically designed for standard industrial voltages.
• Interrupting Capacity: Verify with manufacturer datasheet for specific fault current interruption capabilities.
• Connection Type: Verify with manufacturer datasheet; commonly screw terminals or spring-loaded terminals for DIN rail mounting.
• Operating Temperature Range: Verify with manufacturer datasheet for environmental operating limits.
• Compliance Standards: Verify with manufacturer datasheet for relevant IEC, UL, or other regional certifications.

Applications & Compatibility

This 40A, 3-pole circuit breaker is commonly employed in control panels, motor starter circuits, and distribution boards across various industries. Its C-curve characteristic makes it well-suited for protecting circuits with moderate inductive loads, such as those found in conveyor systems, pump controls, and HVAC equipment, where temporary inrush currents are expected.
