Overview
SIEMENS 5SY(4, 5, 6) Series Miniature Circuit Breakers – UL1077 Supplementary Protector Miniature Circuit Breakers:
Siemens' UL 1077 Supplementary Protectors are designed to provide additional protection along with a branch circuit protection device. Since our 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 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 with out 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.
Features:
High rated breaking capacity of up to 14,000 A
Identical terminals at both sides for an optional infeed from the top or the bottom
No tool required for mounting or dismounting
Separate switch position indication
Supplementary protectors are equipped with a delayed overload/time-dependent thermal release (thermal bimetal) for low overcurrent's and with an instantaneous electromagnetic release for high overload and short-circuit currents. The thermal trip point on all versions is 1.13 to 1.45 times the supplementary protector rating.
Tripping characteristic A, -5:
To protect very sensitive circuits such as semiconductors. Magnetic trip point - 2 to 3 times supplementary protector rating.
Tripping characteristic B, -6:
For European residential circuit protection. Also for protection of computers and electronic equipment. Magnetic trip point
- 3 to 5 times supplementary protector rating.
Tripping characteristic C, -7:
For general device protection in control circuits and all other supplementary circuit protection systems. Magnetic trip point
- 5 to10 times supplementary protector rating.
Tripping characteristic D, -8:
For protection of high inrush loads. Magnetic trip point - 10 to 20 times supplementary protector rating.
