BE1-87T General Information

1-7

Outputs

Output contacts are rated as follows.

Resistive

120/240 Vac

Make 30 A for 0.2 seconds, carry 7 A continuously and break

7 A.

250 Vdc

Make and carry 30 A for 0.2 seconds, carry 7 A continuously

and break 0.3 A.

500 Vdc

Make and carry 15 A for 0.2 seconds, carry 7 A continuously

and break 0.1 A.

Inductive

120/240 Vac, 125/250 Vdc

Make and carry 30 A for 0.2 seconds, carry 7 A continuously

and break 0.3 A, (L/R = 0.04).

Target Indicators

Target indicators may be either internally-operated or current-

operated (operated by a minimum of 0.2 A through the output

trip circuit). When the target is current-operated, the

associated output circuit must be limited to 30 A for 0.2

seconds, 7 A for 2 minutes and 3 A continuously.

Single-Phase Units

Either an internally-operated or a current-operated target is

supplied (as selected by the Style Number) for each trip

output (i.e., the restrained and the unrestrained functions).

Three-Phase Units

Either internally operated or current operated targets (as

selected) indicate the function (restrained or unrestrained)

that caused the trip, and the tripped phase (A, B, C).
