• Siemens’ UL 1077 5SY4125-5 Supplementary Protectors are designed to provide additional protection along with a branch circuit protection device. Since these Supplementary protectors are made to trip faster than a standard UL 489 Circuit Breaker they are able to provide additional protection for more sensitive devices inside the panel. Supplementary protectors can be used in a number of industrial applications such as to provide selectivity for multiple motor control circuits on the secondary side of a control transformer or power supply by allowing the user to quickly find the problem circuit should a fault occur without having to shut down all of the other control circuits. Supplementary protectors may also be used as a local disconnecting means inside the panel when a branch circuit protection device is already present.

  The trip curve A characteristic of the 5SY4125-5 is designed to protect extremely sensitive circuits, for example those involving semiconductors. The magnetic trip point of these breakers is 2 to 3 times the Inrating. The thermal trip point is 1.13 to 1.45 that of the protector rating. Technical Specifications

  • 5SY4125-5 Supplementary protectors are equipped with a delayed overload/ time-dependent thermal release (thermal bimetal) for low overcurrents and with an instantaneous electromagnetic release for high overload and short-circuit currents. The special contact materials used virtually guarantee a long service life and offer a high degree of protection against contact welding.
