Circuit breaker DB90

Function and Circuit breaker use of subscriber BT, for powers lower than 36 kVa:

• protects from the overloads and the short-circuits
• in does version "differential", protect the people against the indirect contacts and the installations against the defects of insulation
• ? in version "selective differential" S allows: to ensure a total selectivity with the differential devices high sensitivity (30 my) installed downstream so that only the departure having the defect of insulation is put not under tension to install a lightning protector immediately downstream from the circuit breaker without risk of inopportune release of this last to take into account the requirements for quality of service required by certain receivers (freezer, computer equipement...).

Characteristics: :

• gauges: adjustable from 10 to 90 A
• ? temperature of use: - 5 to + 40 °C
• thermal release: compensated in temperature
• does differential device classify AC with button-test
• capacity breaking with cos F = 0,7: 2 000 A , for DB90 réf. 13100,13102,13110,13112,13120 and 13123 2 400 A , for DB90 réf. 13103,13104,13105,13106,13115,13116,13121,13122 and 13124
• conform: to standard NF C 62-411 for the instantaneous or selective differential DB90 to standard NF C 62-412 for the nondifferential DB90 with regulations EDF
• protected against inopportune releases
• functions in all the positions and in particular horizontal
• color white RAL 9010
• fixing: by screw ø 4 mm connection by directional terminals with unlosable screws: for does cables copper up to 35 mm 2 neutral located in blue
