Product Description:
Part number 8JSA32.E4055D000-0 is developed by an industrial market giant B & R Automation. Representing a 8JS Synchronous Motors lineup, this module operates as a heavy‑duty circuit breaker engineered for safeguarding machinery. Its three‑pole configuration guarantees uniform disconnection across all phases, preventing an unbalanced loading during fault conditions. Also, the motor’s rated current of 32A accommodates moderate power circuits to easily align with common industrial branch line capacities. A molded case design delivers robustness under mechanical stress that extends operational reliability across repeated switching cycles.
A C‑type tripping characteristic triggers within 5 to 10 times the nominal current which protects against high inrush currents without nuisance trips. A breaking capacity of 10 kA withstands substantial fault currents and limits equipment damage during short‑circuit events. A rated voltage of 400 V AC suits standard low‑voltage distribution networks, enabling compatibility with widespread power infrastructures. The device’s frequency range of 50/60 Hz matches global supply systems which simplifies multinational deployments. The inclusion of DIN-rail mounting secures the breaker within control panels, thus reducing installation effort. From -25°C to +55°C temperature, the module endures harsh environmental variations and maintains high performance.
An IP20 degree of protection guards against finger contacts which preserves internal component integrity. Its terminal capacity of 1–25 mm² accepts both rigid and flexible conductors which supports varied wiring practices. Overall model’s dimensions of 81 mm × 54 mm × 66 mm occupy minimal panel space that also allows compact cabinet designs. Mass of 310 g lightens handling during system assembly and maintains installation workflows. An electrical endurance of 10,000 operations maintains switching reliability over long service intervals that guides preventative maintenance planning. Arc extinction completes within 30 to 150 ms which limits energy let‑through and reduces thermal stress on contacts.
Frequently Asked Questions about 8JSA32.E4055D000-0:
Q: How does the number of poles affect 8JSA32.E4055D000-0?
A: The 3 number of poles ensures all three phases disconnect simultaneously under fault conditions, maintaining system balance and preventing single‑phase operation.
Q: What does the rated current specification imply for 8JSA32.E4055D000-0?
A: Rated Current (in) 32 A defines the maximum continuous current the breaker can carry without tripping, ensuring proper load handling under normal operation.
Q: Why is the tripping characteristic important for 8JSA32.E4055D000-0 motor?
A: The tripping characteristic “C” determines the instantaneous trip threshold relative to rated current, providing selective coordination and rapid disconnection of fault currents.
Q: What benefit does breaking capacity deliver for 8JSA32.E4055D000-0?
A: The motor provides a breaking capacity of 10 kA which indicates the highest short-circuit current the breaker can interrupt safely, protecting circuits during severe fault events.
Q: What does the rated frequency indicate for 8JSA32.E4055D000-0?
A: This rated frequency of 50/60 Hz ensures compatibility with both regional and international power systems, enabling versatile installation.
