Internal
Ignition
Features
Configuration
Closed-ended labyrinth contact block with an
incendive circuit incapable of external ignition
Reed switch sealed against an external
atmosphere
Enclosures capable of withstanding an internal
explosion while preventing external ignition.
Enclosures designed for Class I, Division 1 can
safely be used in Class I, Division 2
Pushbuttons and Indicating Lights

Direct Drive Contacts
•
Contacts can be
mechanically forced
apart if subject to an
arch/fault current.
Escaping
Cooled
Gas
Advantages
Higher continuous carrying amperages—up to 10A
Direct drive contacts—contacts can be forced open
Suitable for use in all enclosures
Best suited for motor control applications
Suitable for low energy level circuits
Suitable for use in all enclosures
Higher level of protection than required for Class I
Division 2
Internal
Ignition
Hermetically Sealed Reed Contact Block
Flat Joint
Depression of plunger
rotates magnet and either
opens/closes contacts.
Contacts can not be
forced apart if subject to
arch/fault current, because no
mechanical connection exists.
Escaping
Cooled
Gas
Hermetically sealed
reed does not allow
external atmosphere to
enter switching chamber.
Disadvantages
May not be suitable for logic level circuits
Lower continuous carrying amperages are not
suitable for motor control applications
(typically 3A to 5A rated)
Contacts cannot be forced open
Permanent magnet attracts metallic dust and
filings that can reduce the electrical creepage
distance between live terminals
Higher material and installation costs
Conduit sealing is still required
Time consuming maintenance
