Preface<\/strong><\/p>\n

This is the first edition of CSA C22.2 No. 268, Power circuit breakers up to 1000 Vac\/1500 Vd, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. <\/p>\n

When published, this Standard will replace CSA TIL D-34. <\/p>\n

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN\/CSA-C22.2 No. 0, General Requirements – Canadian Electrical Code, Part II. <\/p>\n

Certain material in this Standard has been taken from IEEE C37.20.1-2002, Metal Enclosed Low-Voltage Power Circuit Breaker Switchgear. Reprinted with permission from IEEE, 3 Park Avenue, New York, New York, 10016-5997 USA, Copyright 2002, by IEEE. <\/p>\n

Scope<\/strong><\/p>\n

1.1<\/p>\n

This Standard applies to power circuit breakers rated 1000 Vac or less nominal, 1058 Vac (RMS) maximum, and 1500 V dc maximum for use in nonhazardous locations in accordance with the Canadian Electrical Code, Part I. <\/p>\n

1.2<\/p>\n

This Standard applies to power circuit breakers of the following types: <\/p>\n

a) stationary (fixed) mounted or drawout mounted types;
b) manually operated or power operated;
c) with or without electromechanical or solid-state type trip devices;
d) unfused power circuit breakers;
e) power circuit breakers with integrally mounted current limiting fuses;
f) power circuit breakers intended to be connected in series with current limiting fuses in a drawout assembly to form a non integrally fused circuit breaker; and
g) of two-, three-, or four-pole construction. <\/p>\n

1.3<\/p>\n

The circuit breakers covered by this Standard are intended for installation in circuit breaker enclosures, switchboards, switchgear, motor control centres, and similar equipment. The acceptability of the combination of a circuit breaker with respect to any overall enclosure will be determined by evaluation of the complete product assembly. <\/p>\n

1.4<\/p>\n

This Standard covers the requirements for direct acting current and voltage protective functions of <\/p>\n

a) direct-acting overcurrent electromechanical trip devices;
b) direct-acting overcurrent electronic trip systems; and
c) undervoltage trip devices <\/p>\n

1.5<\/p>\n

This Standard does not apply to moulded case and insulated case circuit breakers covered by CSA C22.2 No. 5. <\/p>\n

1.6<\/p>\n

In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Standard. <\/p>\n

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. <\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements. <\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n","protected":false},"excerpt":{"rendered":"
