SIEMENS Molded Case Circuit Breakers

Siemens SCND Series circuit breakers are specially designed to provide electric circuit protection against damages caused by overloads and short-circuit conditions. These devices are calibrated at an ambient temperature of 40 degrees C and feature a non-interchangeable trip capable of resisting mild overloads while instantly responding to severe current surges. They are further integrated with a bolt-on mounting design to ensure ease-of-installation in compact spaces and deliver a maximum interrupt capacity of 65kA at 480VAC. Choose from an extensive array of these circuit breakers available in 800 and 1200A current ratings on Raptor Supplies.

Siemens SHND Series circuit breakers are used for providing protection against current overloads and short-circuit conditions in control panels, switchboards and motor control centres. These UL-listed breakers feature a bolt-on mounting design ensuring smooth installation in compact spaces and LI (long time and instantaneous) current limiting function at a maximum interrupt capacity of 65kA at 480VAC.

Siemens RD Series circuit breakers are designed for protecting control panels, switchboards and motor control centres against current overloads and short-circuit conditions. These units feature a thermal-magnetic trip unit for providing both long-time and instantaneous current limiting functions. They are further integrated with feed-thru mounting facility and box-lug terminals for ease-of-installation and a secure wiring configuration, respectively. Choose from a wide range of these circuit breakers available in amperage ratings of 1600A, 1800A and 2000A on Raptor Supplies.

Siemens SMD Series circuit breakers are designed for limiting let-through current for protecting downstream components in power distribution applications. These molded case circuit breakers feature a bolt-on design for ease-of-installation & wiring, and solid state components for long-term durability & quick response against faulty currents. Selected models feature short time, instantaneous & long time trip functions for reacting against severe short-circuits at once while avoiding tripping on mild overloads. These 3 pole, 800A circuit breakers are available on Raptor Supplies.

Siemens HHED Series circuit breakers are used in electrical distribution systems and panel boards to protect against overloads and short circuits. These circuit breakers safeguard electrical equipment, appliances and wiring from damage caused by excessive currents. They can be operated at voltages up to 600V. These circuit breakers have thermal and magnetic trip units, providing both long-time and instantaneous protection functions. They feature feed-through connection configuration, allowing current to pass through the breaker. These circuit breakers are available in 2 & 3-pole configurations.

Siemens RXD Series circuit breakers are ideal for protecting electrical circuits and machinery against current overloads and short circuits. These devices feature a thermal-magnetic trip mechanism that delivers both long-time and instantaneous current limiting functions against faulty currents. They are integrated with a bolt-on mounting facility for reducing the installation downtime in reverse-feed applications.
