Exchange of the buttons is done by Customer. Information on P type buttons and plugs and plugs on page 167. www.relpol.com.pl R3 Miniature plug-in power relays 96 Mounting R3 relays are offered in versions: • standard, plug-in version with flag indicator and machanical latching (WT). Customer may exchange T type button with P type button (no latching) or with plug (no mechanical operation). P type buttons and plugs and plugs need to ordered saparately • with threaded bolt. Relays R3 are designed for: • screw terminals sockets GZT3 and GZM3 with clip GZT4-0040 or G4 1052, 35 mm DIN rail mount, EN 50022 or on panel mounting. M... type signalling and protection plug-in modules are available with sockets (see page 170). www.relpol.com.pl R3 Miniature plug-in power relays 97 Contact material selection for different load types • AgNi - for resistive or inductive loads, • AgNi/Au 0,2 µm - contact surface protection against oxidation during storage, • AgNi/Au 5 µm - for small resistive loads in control circuits. see Table 1, 2 page 95 * WT - standard features plug-in power relays D, LD, WTD, WTLD - only for DC coils P type buttons and plugs and plugs ordered separately for substition of T type button by Customers themselves: • Button P R4 AC - orange (coils AC) • Button P R4 DC - green (coils DC) • Plug R4 AC - orange (coils AC) • Plug R4 DC - green (coils DC) Information on P type buttons and plugs and plugs on page 167. Note: DC coil polarity for versions equipped with D (arc suppression diode) and L (LED) is fixed. Terminal A1 (13) "+"; terminal A2 (14) "-". Supply polarity is marked on relay housing. Button color represents type of supply: orange for AC coil, green for DC coil. www.relpol.com.pl
