High-magnetic trip circuit breakers. Recommended for applications where high initial inrush current can occur and for individual dimmer applications. vailable as Series 1 with forward box lugs only. (No optional terminations) tripping mechanism is an assembly within the circuit breaker molded case that causes the circuit breaker to open automatically under sustained overload or short circuit conditions. The tripping mechanisms in two- and three-pole circuit breakers operate such that an overcurrent on any pole of the circuit breaker will cause all poles of the circuit breaker to open simultaneously. Thermal and magnetic factory calibration (with current) is performed on each pole of every Square circuit breaker. These mechanisms operate to trip the circuit breaker: Thermal trip Magnetic trip Optional shunt trip accessory (see ccessories, page 12) The sensing system is an integral part of a thermal-magnetic circuit breaker. The sensing system continually monitors current flowing through the circuit breaker. It detects abnormal current conditions and, depending on the magnitude of the current, initiates an inverse-time or an instantaneous tripping response. This action causes the tripping mechanism to open the circuit breaker contacts and interrupt current flow. The speed of the tripping process must be controllable and inversely matched to the severity of the overcurrent. miniature circuit breakers have an over-center toggle mechanism for quick-make, quick-break action with positive handle indication. The handle assumes a position between ON (I) and OFF (O) when the circuit breaker has tripped. 09/2005 2005 Schneider lectric ll Rights Reserved 3 ourtesy of Steven ngineering, Inc. 230 Ryan Way, South San Francisco, 94080-6370 eneral Inquiries: (800) 670-4183 www.stevenengineering.com

Factors influencing this selection include system voltage, continuous current, interrupting rating and frequency. circuit breakers are selected by their ratings. circuit breaker s rating must meet or exceed the parameters of the electrical system on which they are used. Voltage circuit breaker can be rated for alternating current (ac) or direct current (dc) or both. The established voltage rating of a circuit breaker is based on design parameters such as clearance of current carrying parts and dielectric withstand tests both through air and over surfaces. Voltage ratings indicate the maximum voltage for the electrical system on which the circuit breaker can be applied. The circuit breaker must have a voltage rating greater than or equal to the system voltage. When a circuit breaker clears an overcurrent, it does so in two steps: First, the current sensing system identifies the overcurrent and releases the tripping mechanism. This results in a parting of the contacts. Then the circuit breaker must extinguish the voltage arc across the contacts. If the circuit breaker has the correct voltage rating, it can efficiently extinguish this voltage arc. miniature circuit breakers are rated in the following UL 489 voltages, as shown in Table 3: 120/240 Vac 240 Vac 48 Vdc 60 Vdc 277 Vac for QYU, UL 1077 recognized supplementary protector only (not a branch circuit breaker) 6 2005 Schneider lectric ll Rights Reserved 09/2005 ourtesy of Steven ngineering, Inc. 230 Ryan Way, South San Francisco, 94080-6370 eneral Inquiries: (800) 670-4183 www.stevenengineering.com
Miniature ircuit reakers and Switches pplication Information Interrupting The interrupting rating of a circuit breaker is the highest current at rated voltage that the circuit breaker is intended to interrupt under standard test conditions. ircuit breakers must be chosen with interrupting ratings equal to or greater than the maximum available short-circuit current at the point where the circuit breaker is applied in the system (See Table 3). Table 3: Interrupting 1 ircuit reaker Type ontinuous urrent The continuous current rating of a circuit breaker is defined by the National lectrical Manufacturers ssociation (NM) as: The maximum direct current or rms current, in amperes, at rated frequency which a device or assembly will carry continuously without exceeding the specified limits of observable temperature rise. Sometimes referred to as the ampere rating or handle rating of the circuit breaker, the continuous current rating relates to the system current flow under normal conditions. UL Standard 489 states that circuit breakers must carry 100% of their continuous current rating indefinitely (without tripping) at 104 F (40 ) in free air. circuit breakers should be applied, per the N, to carry 80% of their continuous current ratings in the intended enclosure. The continuous current rating is indicated on the handle of each circuit breaker. See Table 1.
