LSiS SP33a Extension Terminal for TS400-630 Circuit Breakers 52.5mm

The LSiS SP33a extension terminal is a precision-engineered accessory specifically designed for integration with TS400-630 series molded case circuit breakers. This component serves as a critical interface for power distribution systems, ensuring that electrical connections remain secure, stable, and compliant with safety standards in demanding industrial and commercial environments. By providing a dedicated extension point, it simplifies the wiring process and enhances the overall reliability of electrical panel configurations.

Advantages

The primary benefit of the LSiS SP33a extension terminal lies in its robust construction and perfect compatibility with the TS400-630 series. It allows for efficient cable management and provides the necessary physical space to accommodate larger conductors, which is often required in high-capacity power distribution setups. Its design minimizes contact resistance, thereby reducing heat generation at connection points and contributing to the longevity of the circuit breaker system.

Suitable for

• Industrial power distribution panels
• Commercial electrical infrastructure
• Upgrading or maintaining TS400-630 circuit breaker installations
• Systems requiring secure termination of heavy-duty electrical cables

When it may not be suitable

This extension terminal is exclusively designed for the LSiS TS400-630 series of molded case circuit breakers. It is not compatible with other circuit breaker models or different frame sizes. Attempting to use this component with incompatible hardware may result in improper electrical contact or mechanical failure.

Key specifications

• Width: 52.5mm
• Compatibility: TS400-630 series molded case circuit breakers
• Function: Extension terminal for electrical connections

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. First, ensure that the power supply to the circuit breaker is completely disconnected and locked out. Align the SP33a terminal with the connection point on the TS400-630 circuit breaker. Secure the terminal using the appropriate fastening hardware, ensuring that all connections are tightened to the manufacturer-specified torque settings to prevent loose contacts.

What to consider before purchase

• Verify the specific model number of your circuit breaker to ensure it belongs to the TS400-630 series.
• Check the available space within your electrical panel to accommodate the 52.5mm width of the terminal.
• Ensure that your cable sizes are compatible with the terminal's capacity.

Usage recommendations

Always inspect the terminal for any signs of physical damage or oxidation before installation. Periodically check the tightness of the connections during routine maintenance to ensure long-term operational safety.
