UL addresses coordination between the branch circuit protective device and the motor starter, and differentiates between Type "1" co-ordination and Type "2" co-ordination. It also provides a method for evaluating the short-circuit performance of these devices. According to UL .

UL Scope and object. This standard applies, when required by the relevant product standard, to switchgear and controlgear hereinafter referred to as "equipment" and intended to be connected to circuits, the rated voltage of which does not exceed 1 V a.c. or 1 V d.c. It does not apply to low-voltage switchgear and. UL is the standard for electromechanical contactors and motor-starters. Introduced in , it is harmonized with the IEC series of standards. While no major technical differences were introduced, Type 1 and Type 2 coordination is addressed. Download our white paper to learn more.
