SIEMENS
High-performance Siemens residual current operated circuit breaker (RCCB), 4-pole, type B, 63A, 300mA. Designed for harsh environments with extended test intervals and short-time-delayed protection.
The Siemens SENTRON 5SV3646-4 is a robust, 4-pole residual current operated circuit breaker (RCCB) engineered for demanding environments. Featuring Type B residual current detection, a high nominal current of 63 A, and a residual current rating of 300 mA, this device ensures superior protection against AC, pulsating DC, and smooth DC fault currents. The short-time-delayed feature prevents unwanted tripping from transient disturbances, and the SIGRES designation guarantees performance in harsh ambient conditions with an extended test interval, reducing maintenance needs. Ideal for industrial applications, machinery, and facilities requiring the highest degree of reliability.
Maximum Safety (Type B): Provides comprehensive protection against AC, pulsating DC, and smooth DC fault currents, essential for circuits with electronic devices (e.g., VFDs, inverters).
High Reliability (Short-Time Delayed): The built-in delay minimizes nuisance tripping from brief voltage or current spikes, ensuring continuous operation.
Reduced Maintenance (SIGRES): Certified for harsh ambient conditions and designed with an extended test interval, significantly lowering operational costs and downtime.
Versatile Application: 4-pole design is suitable for use in three-phase (400 V AC) industrial power systems.
Certified Quality: Part of the Siemens SENTRON series, guaranteeing high quality and compliance with international standards.
Residual current detection with 4-pole configuration.
Rated current: 63A, Rated residual operating current: 300mA.
Short-time-delayed response for selective protection.
Operates at AC voltage: 400V.
SIGRES protection ensures reliability in extreme environmental conditions.
Extended test interval reduces downtime and maintenance costs.
