Thermal-Magnetic Protection for Tmax T5 630
Thermal-magnetic protection combines two established protection principles within a single trip unit. The thermal element responds to sustained overcurrent conditions to protect against overloads, while the magnetic element provides rapid operation when current rises to the specified short-circuit protection level.
The ABB 1SDA055103R1 combines a 500 A rated current with a 2500 A magnetic protection setting. Its four-pole configuration provides 100% neutral protection, making it suitable for compatible T5 630 applications where the neutral conductor requires protection at the same rated-current level as the phase conductors.
Typical Applications
- ABB SACE Tmax T5 630 moulded-case circuit-breaker assemblies.
- Four-pole low-voltage power distribution systems.
- Industrial electrical switchboards.
- Commercial power distribution panels.
- Circuits requiring thermal overload and magnetic short-circuit protection.
- Four-wire installations requiring 100% neutral protection.
