Section 1—Introduction

Advantages

Multi 9 C60 circuit breakers and supplementary protectors provide several features which are

important to OEMs. These include:

•

Small, compact size

•

Easy installation on DIN rails

•

Limits let-thru current

•

Resetability, more convenient than fuses

•

Electrical auxiliaries for control and status information

•

Extensive variety of accessories

Better Protection—Multi 9 supplementary protectors and miniature circuit breakers limit let-through

current, providing faster separation of the component from the fault, thereby reducing system damage.

More Selection—More ratings compatible with low-power electronic circuits are available in the range

from 0.5 to 10 A. Others are provided in convenient steps, up to 63 A for the C60 products.

Reduction of Nuisance Tripping—Available with different trip characteristics to meet system needs:

B, C and D curves, depending on the model.

Panel Space Savings—Multi 9 products are compact. Width per pole is only 0.71 in. (18 mm) for the

C60 circuit breaker. All of the products are built in a consistent format with incremental widths of 0.35

in. (9 mm) (therefore the name Multi 9).

Easy Installation—The Multi 9 products mount easily onto a 35 mm DIN mounting rail. Large box lug

terminals (pressure plate type) are suitable for use with copper wiring up to 2 AWG for C60 circuit

breakers and supplemental protectors.

Reverse Feeding— Reverse feeding of line power is permitted.

Reliability—Each C60 miniature circuit breaker has an endurance of 10,000 operation cycles and

voltage withstand of 6000 V impulse rating.

World-Wide Availability—The Multi 9 products are available and supported throughout the world by

Schneider Electric.
