Siemens 5SY4510-7 SENTRON Miniature Circuit Breaker
Overview
The Siemens 5SY4510-7 is a SENTRON 5SY4 series miniature circuit breaker (MCB) rated for 10 A with a 1-Pole+N configuration and Type C tripping characteristic, providing overload and short-circuit protection with a 10 kA breaking capacity at 230/400 VAC. Note: the source part reference for this listing was originally labeled “Transmitter,” but the genuine Siemens 5SY4510-7 is in fact a miniature circuit breaker in the SENTRON 5SY4 protection device family — not a measurement transmitter — and this page describes the verified, correct product identity.
Seven Star LLC supplies the genuine Siemens 5SY4510-7 SENTRON miniature circuit breaker to electrical contractors, panel builders, and facilities teams across Oman and the GCC. As a partner sourcing authentic Siemens low-voltage protection devices, Seven Star supports customers in Muscat, Sohar, and Salalah with genuine SENTRON MCBs for new distribution board builds, panel upgrades, and like-for-like replacement of aging circuit protection.
Measurement and Operating Principle
The 5SY4510-7 protects its circuit through two complementary tripping mechanisms. A thermal bimetal element responds to sustained overload current, bending in proportion to the heat generated by current flowing through it and tripping the breaker within a time that follows the standard IEC 60898-1 overload curve. A separate electromagnetic trip element responds instantaneously to short-circuit-level currents, and with its Type C characteristic, the 5SY4510-7 trips magnetically between 5 and 10 times its 10 A rated current — between 50 and 100 A — matching the higher inrush currents typical of motor loads, transformers, and lighting circuits without nuisance tripping on start-up.
With a rated breaking capacity of 10 kA at 230 VAC, the Siemens 5SY4510-7 is engineered to safely interrupt substantial short-circuit fault currents without internal damage, isolating the faulted circuit and protecting downstream wiring and equipment. The device carries CE, VDE, and UL 1077 approvals, confirming compliance with both IEC/EN 60898-1 and North American supplementary protector standards, and has a typical mechanical service life of 10,000 operating cycles.
Engineering Design
Mechanically, the Siemens 5SY4510-7 uses Siemens’ compact SENTRON 5SY housing with a standard 70 mm module depth, snapping directly onto 35 mm DIN rail for fast panel assembly. Its 1-Pole+N configuration switches the line conductor while providing a solid, non-switched neutral bus-bar connection, a configuration commonly specified for single-phase final circuits where local codes require neutral disconnection along with the phase conductor. Double terminal chambers accept two conductors of different cross-sections per terminal, simplifying loop-in wiring in densely populated distribution boards.
The breaker’s toggle mechanism includes trip-free operation, meaning the breaker cannot be held closed against a genuine fault by holding the operating handle, and a clear ON/OFF/TRIPPED indication on the handle position lets maintenance staff identify a tripped breaker at a glance during panel inspection. Overvoltage category III and pollution degree 3 ratings confirm the device’s suitability for typical industrial and commercial distribution board environments, including the dusty and high-humidity conditions found across Oman’s coastal and inland industrial zones.

Why Choose Seven Star LLC for Siemens SENTRON Circuit Breakers
A miniature circuit breaker’s rated current and tripping characteristic (Type B, C, or D) have to be selected against the actual inrush and fault-current profile of the circuit it protects, since a mismatched trip curve either nuisance-trips on normal motor or transformer inrush or fails to trip quickly enough during a genuine fault. Seven Star LLC confirms the correct 5SY4510-7 rating and trip characteristic against your specific panel design before order confirmation, drawing on our authorized Siemens partnership across Oman and the wider GCC. We also support panel builders and electrical contractors across Muscat, Sohar, and Salalah with batch procurement for standardized panel designs, so replacement breakers remain consistent across multiple installations sharing the same design.
