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

<\/p>\n

This is the eighth edition of CSA C22.2 No. 77, Motors with inherent overheating protection, part of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1995, 1988, 1976, 1972, 1970, 1957, and 1942.<\/p>\n

<\/p>\n

The major changes in this edition are as follows:<\/p>\n

<\/p>\n

a) Clause 5.5 on motors with electronic protection has been added;<\/p>\n

<\/p>\n

b) Clause 6.4.5.2 on temperature classes has been clarified;<\/p>\n

<\/p>\n

c) the previous Clause 6.6.6 on motors with thermal cutoffs has been deleted;<\/p>\n

<\/p>\n

d) Clause 6.10 on reliability of electronic protection circuit has been added; and<\/p>\n

<\/p>\n

e) an item addressing electronic protection has been added to Clause 7.1.<\/p>\n

<\/p>\n

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

<\/p>\n

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.<\/p>\n

<\/p>\n

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

<\/p>\n

1.1<\/p>\n

This Standard applies to ac and dc motors with inherent overheating protection designed to be used in accordance with the Canadian Electrical Code, Part I, as follows:<\/p>\n

<\/p>\n

a) motors with a voltage rating not exceeding 600 V and with a protective device connected in the motor circuit;<\/p>\n

<\/p>\n

b) impedance-protected motors with a voltage rating not exceeding 600 V; and<\/p>\n

<\/p>\n

c) motors with a voltage rating not exceeding 5000 V and having a protective device connected in an external control circuit with a voltage rating not exceeding 600 V.<\/p>\n

<\/p>\n

1.2<\/p>\n

This Standard applies to motors with protective devices that are responsive to<\/p>\n

<\/p>\n

a) motor temperature alone; or<\/p>\n

<\/p>\n

b) motor temperature and motor current passing through the device but does not apply to motors with protective devices that are responsive to current alone.<\/p>\n

<\/p>\n

1.3<\/p>\n

This Standard does not apply to sealed (hermetic) type motor compressors with inherent overheating protection (see CSA C22.2 No. 140.2).<\/p>\n

<\/p>\n

1.4<\/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

<\/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

<\/p>\n

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

<\/p>\n

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