Residential Circuit Breakers @ Siemens

Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve overcurrent. The following circuit breakers should be utilized to provide further protection.

 

Arc-Fault Circuit Interrupters (AFCI)

Combination Type AFCIs protect against all three possible types of arc fault, line-to-ground, line-to-neutral arcs, and series arcs and thus significantly reduce the risk of electrical fires. They feature a unique LED trip indicator, providing a valuable analysis tool to help electricians pinpoint the type of trip and reduce the time spent debugging the wiring. More info

 

Ground-Fault Circuit Interrupters (GFCI)

GFCIs are an effective means of preventing severe electrical shock. GFCIs are installed to protect areas of the home, such as the kitchen, bathroom or laundry, where electrical appliances or products may come into contact with water. They are designed to protect against severe electrical shock or electrocution from ground faults. Ground faults occur when the electrical current in an appliance strays outside its normal path, and the human body becomes part of the path through which the electrical current may flow.

BL Circuit Breaker

The Siemens BL Circuit Breaker is a panelboard mounted, non-interchangeable trip molded case circuit breaker available in 10-125A, 1-, 2-, and 3-pole. Available in 10KAIC, 22KAIC and 65KAIC interrupting ratings. Also, available are arc-fault, ground-fault and switching neutral breakers.

 
 

Thermal Magnetic Circuit Breakers

Siemens Thermal Magnetic Breakers provide three primary functions: 1) on-off switching, 2) over-current protection, and 3) short-circuit protection.  The over-current protection is provided by a thermal trip element within the breaker.  The short-circuit protection is provided by a magnetic trip element within the breaker.

Surge Protection

 Circuit breakers and surge arresters limit surge voltage by conducting large surge currents safely to ground.  While the voltage of these surges may be high enough to damage you equipment, the associated current is very low.  And since circuit breakers protect against overcurrent not overvltage, surge protection is needed.  Two types of surge protection are point-of-entry and point-of-use.
