SCLD69400NGT - 400Amp Circuit Breaker Description
SCLD69400NGT - 400Amp Circuit Breaker
The Siemens SCLD69400NGT circuit breaker is a 400-amp, 3-pole molded case circuit breaker (MCCB) designed for your compatible commercial and industrial electrical distribution systems. Part of the Siemens SENTRON family, this LD-frame circuit breaker features a 600V AC voltage rating, current-limiting breaking-capacity construction, and a SensiTrip electronic trip unit with LSIG protection functions. For facility managers, electricians, and maintenance professionals working with established electrical equipment, the SCLD69400NGT offers a specific combination of electrical ratings, protection characteristics, and physical dimensions for form, fit, and functional replacement evaluation.
Key Features and Benefits
- 400-Amp Current Rating: Designed for electrical distribution applications requiring a 400A molded case circuit breaker.
- Three-Pole Configuration: Intended for compatible three-phase commercial and industrial electrical systems.
- 600V AC Voltage Rating: Provides a defined voltage rating for evaluating use in qualifying low-voltage installations.
- Siemens SENTRON Product Family: Identifies the breaker as part of Siemens' low-voltage molded case circuit breaker lineup.
- LD-Frame Construction: Supports evaluation of mounting dimensions and equipment compatibility in approved LD-frame installations.
- SensiTrip Electronic Trip Unit: Uses Siemens electronic trip technology with the specified LSIG protection configuration.
- Long-Time Overcurrent Protection: Addresses sustained overload conditions according to the trip unit's operating characteristics.
- Instantaneous Short-Circuit Protection: Responds to high-level short-circuit conditions through the instantaneous trip function.
- Ground-Fault Protection: Incorporates a ground-fault trip function for electrical systems designed to use this protection.
