Magnetic and Hydraulic-Magnetic Circuit Breaker 8330-... Description Single/double pole compact magnetic/hydraulic or magnetic circuit breaker with ratings of 0.02 to 30 A. Upon request, the 8330 in combination with the C14 appliance inlet is also available as completely assembled power entry module (optionally with or without line filter). Typical applications Various applications in telecom/datacom, transportation, marine, generators, power supplies and medical equipment. 1 Features and benefits 8330-... l High performance hydraulic-magnetic breaker with compact and space saving design 35 x 33 mm (1.4 x 1.3 in) for 30 A double-pole Approvals variant l Single or double pole series trip variants. With double pole variant both poles are protected in case of overcurrent on at least one pole both lines are safely disconnected (mandatory in many medical equipment applications) l Different mounting methods like flange, threadneck or snap-in together with a wide variety of actuators provide high flexibility to meet individual device design needs The current data sheet as well as other relevant documents are l Several tripping curves with different time delays: fast magnetic- available on our website: www.e-t-a.com only with instantaneous trip or various magnetic-hydraulic tripping curves for tailored device protection l Trip-free mechanism ensures reliable disconnection of the Compliance circuit even with blocked actuator l Low temperature sensitivity at rated load l Approvals for CBE standards EN60934, UL1077 and CSA C22.2 No. 235 Technical data Technical data Typical life 10 000 operations with rated current I Voltage rating AC 250 V, AC 125 V (50/60 Hz), DC 80 V N Degree of protection Operating area IP40, terminal area IP00 Current rating range 0.02...30 A (IEC 60529/DIN 40050) (see also ordering information table for increments and rupture capacity (1) Ambient Temperature -40C to 85C (-40F to 185F) specifications) (1) Thermal Shock Method 107D, Condition A (five cycles Auxiliary switch rating SPDT (single pole, double throw) -55C to +25C to +85C to +25C). 7 A AC 250 V, (1) Vibration Withstands 0.060 excursion from 7 A (Res) DC 28 V, 10-55 Hz, and 10 Gs 55-500 Hz, at 4 A (Ind.)
