ABB E max series low-voltage molded case circuit breaker (Sace)

Mechanical accessory button protective cover (KE6PG), padlock device (KE6PD1), mechanical counter (KE6MC) to prevent misoperation, lock circuit breaker position, record operation times

Additional auxiliary contacts (KE6A15, 15 sets), position indicator contacts (KE6PS1, 5 sets), extended status monitoring signal, indication of withdrawable circuit breaker position

Interlocking and protective mechanical interlocking (KE6MLP, fixed circuit breaker base), transparent front cover (KE6DC, IP54 protection) achieve multi circuit breaker interlocking control and improve dust and water resistance

Test and Diagnostic Handheld Test Kit (K7TUT, suitable for PR111), Configuration Unit (PR010/T) for on-site testing of trip function and configuration of trip parameters

Model coding rules (taking UL as an example)

Taking "E1S16XXXXXXXXXX" as an example, the key codes have the following meanings to facilitate selection according to requirements:

Frame dimensions: 1=E1 (3 poles), 2=E2 (3 poles), 3=E3 (3 poles), 4=E4 (3 poles), 6=E6 (3 poles); A=E1 (4-pole), B=E2 (4-pole), etc.

Rated current: 08=800A, 12=1200A, 16=1600A, 20=2000A, 32=3200A, 50=5000A.

Breaking ability: B=basic, N=normal, S=standard, H=high, V=extremely high.

Release unit: A=PR111/P-LI, B=PR111/P-LSI, G=PR112/PD-LSI, etc.

Installation method: B=fixed type, D=pull-out type (excluding bracket).

Attachment code: X=no attachment, A=mechanical counter, B=mechanical trip indicator, F=A+B, etc., combined as needed.

Typical application scenarios

Power distribution: used for the main circuit of low-voltage distribution systems, protecting key equipment such as transformers and busbars, and adapting to E4-E6 high current models.

Industrial equipment: provides short-circuit and overload protection for industrial loads such as motors and frequency converters, and E1-E3 small-sized models are suitable for compact layout of switchgear.

Commercial buildings: As the main switch for power distribution, the pull-out design is convenient for later maintenance and replacement.

Compliance and Certification

Safety certification: UL/UL-C certification (applicable to Class I, Groups A-D, Division 2 explosion-proof areas), ATEX certification (Ex nA IIC T4, Zone 2 areas), IEC 60947-2 standard compliance.

Environmental requirements: Compliant with RoHS directive, halogen-free design, reduces harmful substance emissions, suitable for green industrial scenarios.
