7 General Data Ordering Details When placing an order give either the Order Code or Type. In most cases these are completed with other references, e.g. a contactor's coil voltage. This is why the order codes and types figuring in the "Ordering Details" tables have boxes to be completed. Packaging Individual standard packaging Contactors, contactor relays, thermal overload relays and other basic products are supplied in individual packaging. Some small contactors (e.g. B6 and B7 - Section 6) or accessories are in individual batches of "n" pieces as indicated in the "Packaging" column of the "Ordering Details" table. The weight and order code always correspond to a single part. Other products are supplied as a "set" and are thus marked in the "Packaging" column of the "Ordering Details" table. In this case, the weight and order code correspond to a set. Collective packaging To limit the amount of wasted packaging, simplify handling and checking of deliveries, we offer the collective packaging solution. The weight and order code correspond to a single part. Products chosen for this type of packaging are detailed below.

23 BC Contactors Description Application BC contactors are mainly used for controlling 3-phase motors and generally speaking for controlling power circuits corresponding to their operating characteristics up to 690 V a.c. and 440 V d.c. Description of 3-pole or 4-pole contactors: BC 9 - BC 30 For BC and TBC type contactors make sure that the mounting distance specified in the "Ordering Details" pages 2/14, 2/17, 2/19 and 2/24 is respected for "side by side" (position 1) and "stacked" (positions 3 and 4) mounting. The add-on or built-in auxiliary contacts are suitable for low level currents. BC 9, BC 16, TBC 9 and TBC 16 2-stack or 1-stack contactors fitted with a 4-pole CA5 auxiliary contact block ensure positive safety between their auxiliary contacts. Type of magnetic circuit: Solid magnetic circuit with d.c. fed coil. Contact variants: 3-pole contactors with built-in N.O. or N.C. auxiliary contact for BC 9 - BC 25 contactors. 4-pole contactors: 4-pole make or 2-pole make and 2-pole break without built-in auxiliary contacts. 2-stack 3-pole contactors: the first stack is made of a standard contactor and the second stack of an irremovable 4-pole auxiliary contact block. The width does not exceed that of the 1-stack contactor, only the depth is increased. Contactors for specific applications: D.C. operated TBC - types with large voltage range. Variants specific to traction are not given in this catalogue. Please consult us. Quick fixing on mounting rail according to IEC 715 and EN standards: 35 x 7.5 mm, 35 x 15 mm. Dove tail anchoring for surge suppressor assembly. Clear marking of coil d.c. voltage. Terminal screw types: Pozidriv (+,-) N 2; M 3.5 for all BC 9 and BC 16 terminals and BC 18 - BC 30 coil terminals. Pozidriv (+,-) N 2; M 4 for BC 18 and BC 25 main terminals. Pozidriv (+,-) N 2; M 5 for BC 30 main terminals. Holes for screw fixing (screws not supplied). Distance between holes according to EN (contactors for 11 kw motors). Terminal marking according to IEC , EN 50005, EN and NEMA standards. Terminals delivered in open position with captive screws (screws of unused terminals must be tightened). Screwdriver guidance for all terminals makes it possible to use motorized screwdrivers. All terminals provide protection against accidental direct contact with live parts according to VDE 06 - Part. 0. Stops for attaching front-mounted accessories. Location of function marker.
