Cutler Hammer SPCL1C05 Supplementary Protector Circuit Breaker

The Cutler Hammer SPCL1C05 is a single-pole, 5-ampere supplementary protector circuit breaker designed to provide reliable overcurrent protection within electrical equipment and appliances. Recognized under UL 1077 standards, this device is intended for applications where branch circuit protection has already been provided or is not required.

Key Features

• Current Rating: 5 Amperes
• Voltage Rating: 277 VAC
• Interrupting Capacity: 10 kA
• Trip Curve: C Curve (5 to 10 times the rated current), suitable for general-purpose industrial applications requiring higher inrush tolerance
• Mounting: Quick snap-on clip design for easy installation on 35 mm DIN rail
• Design: Light gray case with a charcoal gray handle
• Protection: IP20 degree of protection
• Terminal Capacity: Suitable for single-core, standard, and flexible conductors from #14 to #6 AWG (Cu), with a recommended torque of 27 inch-pounds

Applications

The SPCL1C05 is ideal for providing supplementary overcurrent protection in various applications, including:

• Control power transformers
• Relays
• Contactor coils
• Lighting circuits

Its current-limiting design ensures fast short-circuit interruption, reducing let-through energy and minimizing potential damage to the circuit.

Installation and Safety

The SPCL1C05 features a quick snap-on clip design, allowing for effortless installation on standard 35 mm DIN rails. The breaker handle includes a unique center trip “reset” position that clearly indicates an overcurrent trip. Additionally, the “OFF” (O) and “ON” (I) handle positions are visually indicated by red and green flags, respectively, enhancing operational safety and status identification.

With its robust design and reliable performance, the Cutler Hammer SPCL1C05 Supplementary Protector Circuit Breaker is a dependable choice for safeguarding electrical systems against overcurrent conditions.
