Main Power Input & Output (Power Terminals)

3-pole design intended for three-phase AC applications.

Maximum rated operating voltage reaches 600 V AC.

The frame continuous current rating is 250 A; operating current can be configured with the front-mounted SRPF rating plug.

Line-side terminals serve as the power input for incoming three-phase supply.

Load-side terminals act as power output to downstream electrical loads.

The breaker allows reverse-feed wiring arrangement.

Main Circuit Electrical Parameters

Interrupting Rating

65 kA at 240 V AC

35 kA at 480 V AC

22 kA at 600 V AC

Equipped with an embedded solid-state RMS trip unit that delivers LSI protection, including long-time delay protection, adjustable short-time delay protection and configurable instantaneous short-circuit protection.

Auxiliary Signal Interface (Optional Accessories)

Auxiliary Switch Input

Standard configuration excludes external control inputs for remote direct tripping. Shunt trip coil or undervoltage release coil can be fitted as optional auxiliary input assemblies.

Auxiliary Contact Output

Form-A or Form-C auxiliary contacts are available for remote status feedback.

Contact rating: 240 V AC, 5 A resistive load.

These contacts transmit open/closed status indicating whether the breaker is switched ON or OFF.

Optional alarm contact provides signal output upon thermal overload or fault-induced tripping.

Internal Sampling & Trip Circuit

Current transformer sensors are installed on each phase to continuously measure RMS values of three-phase currents.

Captured sampling signals are delivered to the integrated digital trip logic for fault evaluation. No external analog signal terminals are provided.

Case 1: Main and Feeder Protection for Industrial Power Distribution Panels

The SFHA36AT0250 functions as the main incoming circuit breaker or branch feeder protection device within three-phase industrial distribution panels. It provides multi-level LSI protection for power circuits of production lines. The front-mounted SRPF rating plug supports flexible rated current tuning to accommodate loads between 100 A and 250 A. Its high interrupting capacity reliably isolates short-circuit faults and restricts fault spreading throughout the power network. This breaker is extensively applied in manufacturing facilities, chemical plants and auxiliary power systems for mining sites.

Case 2: Protection for Medium and Large Three-phase Motor Circuits

It serves as protective equipment for motor circuits driving high-power fans, water pumps, compressors and conveyor equipment. The built-in solid-state RMS trip unit accurately measures true RMS current and prevents unwanted tripping triggered by motor startup inrush current. Combined with contactors and thermal relays, it establishes a comprehensive motor protection scheme covering long-time overload, adjustable short-time delay and instantaneous short-circuit protection. It is applicable to continuously operating motor loads within the 250 A frame rating.

Case 3: Input and Output Protection for UPS Uninterruptible Power Supply Systems

This breaker is mounted on the AC input, bypass loop and output feeder of industrial UPS and static transfer switch cabinets, performing the roles of an isolating switch and fault protection breaker. Its compatibility with reverse-feed wiring meets the bidirectional power flow features of UPS systems. Optional auxiliary contacts transmit breaker on/off status and fault trip signals to the upper SCADA monitoring platform for remote supervision. Typical scenarios include auxiliary power systems in data centers and standby power setups for critical facilities.

Case 4: Power Distribution Systems in Multi-story Commercial Buildings

It is installed in basement main distribution rooms and floor sub-distribution panels of shopping centers, office buildings and logistics warehouses to safeguard central air conditioning units, large HVAC devices and general power feeders. The compact bolt-on mounting design fits standard commercial electrical cabinets. The product complies with UL and CSA standards and satisfies specification requirements for low-voltage power distribution in North America.

Case 5: Retrofit and Upgrade of Legacy GE Spectra Power Distribution Equipment

The unit is utilized for replacement and refurbishment of aging GE Spectra power panels, motor control centers (MCC) and switchboards. Matched installation dimensions and consistent accessory compatibility allow direct drop-in replacement without cabinet modifications. Engineering teams deploy this model during equipment overhaul projects to extend the service life of existing power distribution infrastructure and cut overall renovation expenses.

Case 6: Auxiliary Circuit and Transformer Secondary Side Protection for Generators

It is deployed for secondary circuit protection of distribution transformers and auxiliary circuits of small and medium-sized synchronous generators. The configurable short-time delay feature enables protection coordination between upstream and downstream breakers to implement selective tripping. If a fault occurs on a local branch, only the faulty circuit will be disconnected, while power supply to other intact loads remains uninterrupted.
